Is it necessary to replace tires when changing rims?

[JordanDella]

Whether tires need to be replaced when changing rims depends on the situation: 1. If replacing rims of the same model, there is no need to change the tires; 2. If replacing rims of a different model, then it is necessary to replace the tires to match the new rims. The rim is the rotating part of the wheel hub connected by pillars to the inner contour of the tire, serving as the central metal component that supports the tire and mounts onto the axle, also known as the wheel ring, steel ring, or hub. Tires are circular elastic rubber products assembled on various vehicles or machinery, mounted on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain driving performance. They operate under complex and demanding conditions, enduring various deformations, loads, and temperature extremes during driving, with high load-bearing, traction, and cushioning capabilities.
